Answer:
Step-by-step explanation:
The composite has 2 parts:
Part 1- a parallelogram with 2 dimensions 23 and 15, the height 14cm
Part 2- a trapezoid with two bases of 15 and 34, height of 19.
[tex]S=S_{1}+S_{2} \\ S_{1}=14*23= 322\\\\S_{2}=\frac{1}{2}(15+34)*19 =\frac{49*19}{2}=465.5\\ S=322+465.5=787.5\\[/tex]
